Building a Bear-Proof Suit

On August 4, 1984, Troy Hurtubise was hiking in central British Columbia when he came face-to-face with a grizzly bear. The grizzly knocked the 20-year-old sportsman down, his .22 rifle careening out of reach. Struggling to his feet, he drew his knife.

The bear, Hurtubise claims, seemed to contemplate its chances before disappearing into the woods. A conservationist later told him that if any cubs had been present, he would’ve been mauled.

To the grizzly, it was a forgettable encounter with a bothersome human. To Hurtubise, it was a revelation. The Ontario native became obsessed with designing armor that could withstand a full-blown attack. Inspired by the chain mail worn by shark researchers, he began consulting with experts on how to test his ideas. The suit’s seven-year development was chronicled in the 1996 documentary Project Grizzly, a favorite of Quentin Tarantino’s.

But not all has gone well for Hurtubise. Now 50, the self-proclaimed eccentric doesn’t use schematics and often can’t explain why his inventions—fireproof paste, a bulletproof shield, a light he claims shrinks tumors—work. Over the years, he’s been forced to declare bankruptcy, sell his prototypes on eBay, and even pawn his wedding ring to make up for the debts run up by his obsessive ambitions.

Since Hurtubise lacks financial or university backing, most dismiss his notions as fanciful or downright senseless; others believe his ideas could save lives. “My wife has said, ‘If you’d just invent some simple refrigerator magnet and do an infomercial, we’d be rich,’ ” Hurtubise says. “But I don’t know how to do that. I just build what I see in my head and know it’s going to work.”

Armor Up

Years after his encounter with the bear, Hurtubise was watching RoboCop when he was struck by the idea of body armor. He thought there should be a protective suit that would allow researchers to test so-called bear-proof sprays and safely observe grizzly behavior. He spent the next seven years (and $150,000) constructing a series of suits he dubbed Ursus Mark. The 7'2" Mark VI—a blend of air cushioning, titanium, and duct tape—successfully endured makeshift trials in which it was hit by a pickup truck and beaten by bikers armed with baseball bats, as depicted in Project Grizzly. But the armor weighed as much as Hurtubise himself: 150 pounds.

“My only complaint was that the filmmakers didn’t show five minutes of science behind it all,” he says. “Being able to get hit by the truck took years of development.”

Ultimately, Hurtubise’s rematch with a grizzly never came to be. During filming, he was forced to abandon his efforts because the suit was too heavy and he was unable to remain upright on uneven ground. In 2002, a trainer allowed him inside a cage with a Kodiak, which was too confused by Hurtubise’s appearance to approach him.

“She was so terrified, she urinated,” Hurtubise recalls. “I didn’t look human enough.” Limited mobility and questionable usefulness combined to doom the Mark series. “We would never use a suit like that,” says Lana Ciarniello, PhD, a bear behavioral expert. “A solid knowledge of bear behavior is the best thing one can use to avoid being attacked, [which is] rare.”

Nonetheless, the armor brought Hurtubise fame. In addition to the documentary, he was recruited for Japanese game shows, and he inspired a 2003 episode of The Simpsons where Homer constructs a bear-proof suit. He even filmed an Audi commercial. Of course, Hurtubise quickly reinvested the proceeds in his pursuits.

After Hurtubise hung up his bear ambitions, he turned his attention toward other inventions. He had a brother in the military, which piqued his interested in flexible armor, and he believed a suit styled after the one in the videogame Halo would keep soldiers and law enforcement better protected. So Hurtubise invented a suit dubbed the Trojan and performed his trademark experiments, enlisting retired military marksman Keith Cunningham—who had “covered” Hurtubise during his bear expeditions with nonlethal rounds—to help with field tests.

Once, Cunningham recalls, Hurtubise wanted to be shot point-blank, believing his armor-plated chest could take the bullet. “But it’s illegal in our province to point a loaded weapon at someone,” Cunningham says. “So we took the plate out. I shot at it, and the bullet went right through. He turned ashen gray.”

Hurtubise tweaked the Trojan, which he debuted in 2007, to little notice. Eventually, he offered his design to the Canadian military for free, but it can take years for armed forces to evaluate new technology. And existing contracts with equipment vendors render it near impossible for independent inventors without backing or references to succeed. “With industrial military, contracts are sewn up, and they don’t want anyone stepping on toes,” he says. “Engineers pick my brain, but I can’t be affiliated with them. I’m a loose cannon, and my methodology is backward.” Even so, many of Hurtubise’s inventions have grabbed headlines. His fire paste, a gooey substance that hardens to resist flame, was documented by Canada’s Discovery Channel as standing up to temperatures in excess of 3,600° F. Hurtubise held a blowtorch to his helmeted head for 10 minutes to prove it. NASA, he says, was interested but never followed up.

During a demonstration for his blast blanket, a plate meant to absorb heavy firepower, a crowd watched as Cunningham shot round after round of 12-gauge shotgun shells into it. When it finally budged, it only fell over; the glass behind it was unharmed. “I told cops about it every chance I got,” Cunningham says. “Imagine having that on the doors of patrol vehicles for protection or under military transports. I told them, ‘Try to look past Troy’."

There was a reason for Cunningham’s caution: Hurtubise looks more like a mountain man than an esteemed inventor. Worse, his claims sometimes stretch the boundaries of reason. Hurtubise garnered skeptical looks when he announced that his God Light device had shrunk his sister-in-law’s cysts as well as tumors in mice. He even believes it can cure Parkinson’s. “Light is extremely effective against certain cancers,” he says. “All I did was take all spectrums of light, electromagnetic radiation, and put them together. And it works. I don’t know why, but it does.”

Hurtubise’s claims have never been validated by an outside auditor, in large part because subjecting a group of sick people to a makeshift electromagnetic beam stretches ethical considerations. When Hurtubise turned the light on himself, he experienced what he calls the Hyde effect. His hair began falling out, and he lost 20 pounds. Then the God Light stopped working. Hurtubise has yet to find the money to resurrect it.

Invent and Invent Again

Today, Hurtubise operates a scrapyard in Ontario and dismisses notions of patents (“the stuff is too easy to duplicate, and it costs $80,000 to file an application”). He rejects offers to outright sell his creations—like fire paste—because he frequently sells off shares to fund their development. “By the time I got fire paste to the point of testing, 70 percent of it was owned by investors,” he says. “So when a university wants it, I have only 30 percent left. They’re not interested in that.” And yet, Hurtubise can’t stop inventing. He still feels compelled to put in 21-hour days refining his projects. His current plan is to find funding for the Apache, the latest version of his Trojan suit, which he says protects 93 percent of a user’s body and offers 96 percent flexibility. A prototype will cost $70,000. “It’ll take six to eight months to build by hand. I’ll try to market it to law enforcement like SWAT.” He needs another $100,000 to rebuild the God Light, renamed the EMR-5, which he now claims will only cure breast cancer. He wants to take it to Johns Hopkins for testing.

As for Hurtubise’s legacy, it’s hard to predict. There’s a chance he’ll join the long list of inventors who were once disparaged until time proved them correct. Even the airborne Wright brothers were thought to have faked their maiden flights. If that’s Hurtubise’s fate, he seems comfortable with it. “I’ve been called a maverick, a nutcase, everything,” he says. “It never bothered me. Without imagination, science is nothing.”

As the site of the ancient city of Thebes, the modern-day Egyptian city of Luxor is filled with archaeological treasures. But until recently, two forgotten tombs—both located in the necropolis of Dra' Abu el-Naga, an important non-royal cemetery—hadn’t been fully explored. Now, National Geographic reports that experts have finally excavated these burial sites and discovered a 3500-year-old mummy, along with ornate funerary goods and colorful murals.

While excavating one of the two tombs, known as Kampp 150, experts found linen-wrapped remains that Egypt's Ministry of Antiquities believes belong to either "a person named Djehuty Mes, whose name was engraved on one of the walls ... [or] the scribe Maati, as his name and the name of his wife Mehi were inscribed on 50 funerary cones found in the tomb's rectangular chamber."

In addition to the mummy, archaeologists discovered wooden statues, masks, earthen pots, a cache of some 450 statuettes, and around 100 funerary cones—conical mud objects, which were often positioned outside a tomb's center, and could have served as identifying markers or as offerings—inside Kampp 150.

The Associated Press reported that the second tomb, known as Kampp 161, is thought to be approximately 3400 years old—about 100 years newer than its neighboring chamber—as its design is characteristic of other such structures dating back to the reigns of Amenhotep II and Thutmose IV.

Inside Kampp 161, archaeologists discovered wooden funerary masks, a decorated coffin, furniture shards, and the mural of a festival or party depicting the tomb's unknown resident and his wife receiving ceremonial offerings.

German scholar Friederike Kampp-Seyfried surveyed and numbered both tombs in the 1990s, which is how they got their names, but she did not fully excavate nor enter either one.

Officials celebrated the rediscovery of the tombs on Saturday, December 9, when they publicly announced the archaeological finds. They hope that discoveries like these will entice foreign travelers to visit Egypt, as political unrest has harmed the country's tourism industry in recent years.

Ready to have your mind boggled? Take a look at the image above. What shape are the lines? Do they look like curves, or zigzags?

The image, spotted by Digg, is a new type of optical illusion published in the aptly named journal i-Perception. Discovered by Japanese psychologist Kohske Takahashi, it’s called the “curvature blindness illusion,” because—spoiler—the contrast of the lines against the gray background makes our eye see some of the lines as zigzags when, in fact, they’re all smooth curves.

The illusion relies on a few different factors, according to the three experiments Takahashi conducted. For it to work, the lines have to change contrast just at or after the peak of the curve, reversing the contrast against the background. You’ll notice that the zigzags only appear against the gray section of the background, and even against that gray background, not every line looks angled. The lines that look curvy change contrast midway between the peaks and the valleys of the line, whereas the lines that look like they contain sharp angles change contrast right at the peak and valley. The curve has to be relatively gentle, too.
